Trendy Africa Boutique review for DHL Express (Official)

I am very concern. i like shipping with DHL from my website. However, 2 packages have been delivered to the wrong address over the past year. there is no one to speak to. customer service is so poor. most recently is about $400 goods ship to wrong address and signed by wrong receiver. i filed a claim and no response so far. what is going on with DHL??
